LOOM-SI-IU'TTLE.

Specification of Letters Patent.

Patented Aug. 19,1913.

Original application filed July 27, 1909, Serial No. 509,861. Dividedand this application filed December 1, 1910. Serial No. 595,020.

To all whom it may concern:

Be it known that I, ALFRED Isrrnnwoon, a citizen of the United States,and a resident of New Bedford, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Loom-Shuttles, of which the follpwing is a specification.

lily invention relates to loom shuttles, and more particularly to adelivery eye adapted to be used with self-threading shuttles such as areused in automatic filling-replenishing looms or with common shuttles,and the objcct thereof is to improve the construction of such eye in themanner hereinafter set forth.

One embodiment of my invention is shown in the drawings which accompanyand form part of this specification, but it will be understood thatvarious modifications may be made therein without departing from theprinciple of my invention.

In the drawingsFigure 1 is a plan view of the delivery end of a commonshuttle provided with my improved delivery eye. Fig. 2 is a side view ofthe shuttle shown in Fig. 1. Fig. 3 represents the blank from which theeye may be formed. Fig. 4 is a plan view of said eye. Fig. 5 is atransverse section taken on the line ll11 of Fig. at. Fig. 6 is a planview of one form of guard that may be used with the shuttle shown inFig. 1. Fig. 7 is an edge view of said guard. Fig. 8 is a front view ofsaid guard.

In the particular drawings selected for illustrating my invention 1represents a common shuttle provided with the usual metallic tip 2. Theeye 7 is inserted transversely in the throat of the shuttle which isprovided with the slot 11 extending as shown diagonally across the topof the shuttlc and having its inner end terminating at the lower end ofthe circumferential slot 8 of the eye. The slot 11 intersects thelongitudinal slot 12 formed in the front side of the shuttle.

The eye -7 is preferably formed from a blank shown in Fig. 3 and isapproximately circular in section throughout a portion of its length.This eye is provided with the above mentioned slot 8 which intersectsthe longitudinal slot 8 and the latter terminates in a circular hole iion the upper side of the eye. The inner lip 13 is formed by bending theportion of the blank shown at 13 in Fig. 3 under the surface of the eyeso that the lip underlies a portion of the longitudinal slot 8 as mostclearly shown in Fig. 4-. The delivery-end of the eye near the frontwall of the shuttle is provided with two downwardly extending curvedlips 15 and 16 formed by bending the portions of. the blank designatedas 15 and 1 6 in Fig. 3.

In order to thread the shuttle, the operator will grasp one end of thethread A and pass it through the slot 11, thereby bringing it into theslot 8 of the eye, and will then draw it inwardly through the slot 12,thereby causing the thread to enter the slot 8, to pass under the lip 13and up into the hole 14, and finally to pass between the shuttle and thelip 15, whereupon the shuttle is threaded and the position of the threadin the shuttle is as shown in Fig. 1 at A A. The downwardly-extendinglips 15 and l6prevent the thread from leaving the eye in a manner thatwill be obvious.

In order to prevent the outward ballooning of the thread, I may employ aguard which may also perform the function of a tension device. Thisguard which is shown in detail in Figs. 6, 7 and 8, consists of a base20 which is held in adjustable position in two slots cut in the throatof the shuttle, an upwardly-extending piece 20 substantially at rightangles to said base and an outwardly-extending flat piece 17 the corner18 of which enters a groove in the shuttle above the eye 7 and is firmlyheld in position thereby. The piece 17 is provided with arearwardly-extending lip 19, which as shown in Fig. 1, fits loosely intoa slot in the shuttle, the slot being large enough to permit the threadto pass over said lip. 22 is an eye which I may call a tension-eyeconsisting of a slit in the inward end of the guard, and 21 is anupwardly.-extending guard for said eye. The eye 22 is so positioned withrespect to the hole 1% in the top of the eye 7 as to put the threadunder tension, and in the present instance the eye 22 is placed belowthe hole 14: so that the thread must pass up an incline from the eye 22to the top of the eye 7. The tension on the thread may be regulated byturning the eye 7 in its socket. hen the guard just described isemployed, the thread is broughtthrough the slot 11 and then the inwardmovement of the thread through the slot 12 will draw the thread over thelip 19 and in the slot into which said lip projects, and then over theguard. 21 and into the eye 22 and finally into the eye 7 in the mannerhereinbetore described.

It will be understood from the above description that the eye 7 may beemploy-ed With an automatic or a common shuttle and that any suitabletension device may be used, and furthermore that if it be used. in aconnnon shuttle, the latter may be proided with the combined guard andtension device described in connection with F G, 7 and S as shown inFigs. 1 and 2.

This application is a division of my appiication Serial No. 509 861,filed July 27, 1.909.

I claim:

1. A loom-shuttle having a removable delivery-eye inserted transverselyin the throat of the shuttle and provided With a slot a lip in theinterior of said eye adjacent to and passing under said slot, said lipbeing adapted to prevent the filling-thread from leaving said eye, andtwo downwardly-extending lips secured to the delivery-end of said eyeatthe front Wall of said shuttle.

2. A loom-shuttle having a removable delivery-eye inserted transverselyin the throat of the shuttle and provided With a slot, and twodoivnwardly-extending lips secured to the delivery-end of said eye atthe front- Wall of said shuttle.

it loom-shuttle having a removable delivery-eye inserted transversely inthe throat of the shuttle and provided With a slot, one portion of saidslotbeing circumferential and the other portion thereof at right, anglesto the first portion being longitudinal of said eye, a lip in theinterior of said eye adjacent to and passing under the longitudinalportion of said slot, and two downu'ardly-extending lips secured to thedo livery-end of said eye at the front Wall of said shuttle.

ii.- A loon'i-shuttle having a removable delivery-eye insert-edtransversely in the throat of the shuttle and provided. with a slot oneportion of said slot being circumferential and the other portion atright angles to the first portion being longitudinal of the eye, and twodownivardly-extending lips secured to the delivery-end of said eye atthe front wall of said shuttle.

In testimony whereof, I have hereunto subscribed my name this 25 day ofNov. 1910.
